MELBOURNE Lord Mayor Robert Doyle is reaching the limit of his frustration with citizens abusing the city’s dockless bike share scheme.

The bicycles have been popping up in weird and wonderful places all around the city, including the top of public toilets, in trees, and even taped to lamp posts. Several have also been seen floating down the Yarra river.

“We work hard to keep the city free of clutter,” the Lord Mayor told the Herald Sun. “They are clutter and that must be fixed.”

The bike share scheme is part of Melbourne’s modern transport plan. Unlike the blue bicycles from Melbourne Bike Share, which have to be returned to a designated bike rack, the oBikes can be left anywhere convenient.

Or inconvenient, as the case may be.

Several hundred shiny yellow and grey bikes, which can be unlocked simply with a mobile phone app, appeared on the city’s streets in June. They cost just $1.99 for 30 minutes including a helmet, making them a cheap, easy and green way to easy traffic congestion in the inner city.

“We know how people want to use bicycles now,” Councillor Nicolas Gilley told Fairfax when they were released. “We want people to be able to have cheap bikes, put them everywhere and have people able to use them.”

However, frustrated residents are now taking to social media to vent their frustration at the large number of bikes being left in public spaces. In addition to the crazy stunts, many bicycles are simply dumped on footpaths, at the bottom of staircases, or in long rows that topple over like dominoes.

The council and operators of the Singapore-based oBike scheme have been in talks for weeks to fix the problem, but if no solution can be found, it will be axed.
